I think....I can't seem to find anything written about this place in Ireland. I just remember my uncle saying that it was called what sounded like "The Berm" and also that it was a large volcanic geological structure that has a diverse variety of flora because of the contrast of volcanic warmth and Irish chill.
Also, this is a previously published photo that I edited in Photoshop for tone and contrast etc. You may view the original image here: http://www.pbase.com/khtaylor/image/44512995
